Subject: High Vibration and Unstable Flight on F450 Drone with Pixhawk 2.4.8

Hi everyone,

I’m having trouble with my F450 drone. It has high vibrations and is very unstable and shaky during flight. I’m using a Pixhawk 2.4.8 flashed with the latest PX4 software.

Here are some details:

  • The drone can fly but it’s very unstable.
  • I don’t think there’s a problem with the chassis.
  • I’m currently unable to use my telemetry because of incompatible connectors.
  • I’m not using a GPS.

I’ve checked the propellers and motors, but everything seems fine.

Here are two log files from my recent flights for reference:

What could be causing this issue? Any advice on how to fix it?

I secured the pixhawk with more zip ties, and calibrated everything again before the mentioned log files

Did you tie the zip ties along with the frame or in the vibration isolator alone, if it’s the former remove the zip tie and try to fly then

bad PID tuning is my guess
